Glenn has missed the past five games with a foot and ankle injury that has bothered him since training camp. McDermott said Friday that Glenn is scheduled to have surgery soon.

McDermott also says quarterback Tyrod Taylor will start for the Bills (7-6) this week against Miami (6-7). Taylor sat out Buffalo's 13-7 overtime win over the Indianapolis Colts last week with a knee injury.

Rookie backup quarterback Nathan Peterman is still in the league's concussion protocol after getting hurt last week.

McDermott says the Bills have not yet made a move to fill Glenn's spot on the roster. Rookie Dion Dawkins has been starting at left tackle while has been out.
